Perhaps you should try some spelling variations:
things during » things using, things sharing, thing hiring
when adding » why adding, when handling, when adapting
wang dan » wang yan, wang ban, wang yidan
dan yang » daun yang, tan yang, wang yang
ai first » i first, ii first, mali first
dong bin » dong sin, dong di, dann bin

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang dan yang ((2 first) or (ai first)) ((when adding) or (things during)) dong bin ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang dan yang ((2 first) OR (ai first)) ((when adding) OR (things during)) dong bin ;.
• Adding a wildcard symbol may retrieve word variants: wang dan yang ((2 first) or (ai first)) ((when adding) or (things during)) dong bin ;*.
